My JD lt150 has CV15s Motor. I am look to find the carb settings. After setting covered all winter I went to get it ready for this years projects. Poured fresh gas into it then replaced the Fuel & Air filter. The Oil & Filter were changed a few days prior to being parked for the winter,with the gas tanked drained. I tried to start it and it fired ran then shut off. It will not run, but attempts to run when trying to re-start it. I checked the fuel pump and it is working. I took off and checked the fuel bowl under the carb and it had the fresh fuel in it.

What other things should I try to troubleshoot the problem? This machine belongs to the wife who is concerned with it not running.
